you might want to venture out of the back 40 towards Europe and try their non-cold beer before commenting.
There are a whole lot less preservatives in their beer simply because they dont need it. It doesnt last long enough to go bad. When your grocery shopping carts have a special rack specifically designed to hold a case of beer, beer doesnt sit on a shelf very long. The quality of the beer is different and so very smooth.
One of my first encounters with "warm" beer was when I was on the airplane going to Germany. I ordered a Heineken (that's what was offered) and when I got the can I could feel is wasnt cold at all. "This is going to suck" I thought but I took that first swig and it was the smoothest beer I've ever had. No burn, no aftertaste. Just good beer. Chilled a bit but not cold.
I go to Germany about once a year and there are some brands I just dont like much the same here in the states so cold, chilled, or hot I wont order them. I dont want my German beers "cold", I want them room temp or slightly chilled. On the other hand, please cool my American beer as much as possible.
